Sliver coiler



SLIVER cornea Charles W. Walter, Griiiin, and Allen D. Layson, Hampton, Ga., assignors toSouthern States Equipment Corporation, a corporation of Georgia Application May 10, 1957, Serial No. 658,371 6 '(Cl.'19--'159) This invention relates to sliver coilers and more particularly to coilers which are adapted-for easy installation and use with either right or left-hand card machines.

Conventional coilers having a vertical pedestal mounted on a base With a head mounted atop the pedestal and with a drive shaft rotatably mounted within the vertical pedestal are mounted adjacent an associated card machine. The coiler drive shaft is coupled with a drive shaft driven by and forming a part of the associated card machine. Such drive shafts are normally parallel to the-axes of the main card cylinder and its doffer and the drive shaft is coupled with the vertical coiler shaft on the side of the pedestal generally opposite from the side thereof toward whichthe head and base of the coiler extend. If the card is of the right-hand type, a coiler base and head are disposed with respect to the card machine drive shaft atjan angle which is "opposite from the angle required if the card machine is of the left-hand type.

A principal object of our invention is to provide an improved coiler which is universally applicable to rightor left-hand card machines.

Another object of our invention is the provision of a coiler which is readily applicable to right or left-hand coilers, which is characterized by a unitary construction, and which is therefore incapable of maladjustment due to vibration.

Still another object of this invention'is to provide an improved coiler Whose angular relation to the drive shaft mounted on the associated card machine can be readily adjusted by shifting the entire coiler bodily relative to the drive shaft and card machine.

I A further object of this invention is the provision of an improved coupling between a pair of interrelated'shafts and their housings which are disposed at a given angle to each otherin one plane whereby angular adjustment between the shafts and their housings may be readily effected in another plane substantially normal to theone plane. I

The invention in one form as applied to a sliver coiler comprises a vertical hollow pedestal having an exterior surface of circular configuration, an adapter having a surface convicted to conform with the circular configuration of the pedestal, a driven shaft coaxially disposed Within the pedestal, a driving shaft extending journally through the adapter and normal to the shaft within the pedestal, and holding means for securing the adapter and the driving shaft in a predetermined angular relation to the pedestal and its shaft, whereby rotation of'the pedestal about its axis relative to the adapter does not alter the locus of the axis of the shaft within .the pedestal. V I The invention will be better understood from 'th'e 'fol-' lowing detailed description taken in conjunction with the accompanying drawings in which Fig. 1 is a side view 'lof' a sliver coiler embodying the invention; Fig. 2 is an enlarged cross-sectional view of the coiler pedestal. and "associated parts taken along the line 2-2 of '1; Fig. '3

Patented Apr. 26, 1950 2 v is an enlarged view taken along the line 33 of Fig. I; and in which Fig. 4 is a cross-sectional view'taken along the line 4-4 of Fig. 2. Fig. 2. is also a cross-sectional view taken along the line 2-2 of Fig. 4.

With reference to Fig. 1 the numeral 1 is used to designa'te a base portion on which is mounted a'vertically disposed pedestal generally designated by the numeral 2. Atop the pedestal 2 is mounted a head generally designated by the numeral 3. Disposed on the base 1 is a rotatable platform 4 on which a sliver receiving can 5 is mounted. The pedestal 2 is afiixed to an associated card machine, a portion of which is designated in Fig. -'1 by the numeral 6. A drive shaft 7 forms a part of the card machine and is interrelated with a vertically disposed shaft mounted within the pedestal 2. Thus rotation of shaft 7 imparts rotation to the shaft within the pedestal 2 and thereby operates the mechanism of head 3 and rotates the platform 4 to perform a coiling operation in known manner.

Since the parts 6 and 7 of the associated card machine are fixed in position irrespective of whether the particular card machine is of the right-hand or left-hand type, it is necessary when applying a coiler to a card machine to rotate the coiler bodily about the axis of pedestal 2 in order to accommodate the space afforded by the particular card machine.

If the card machine is of the left-hand type, the coiler must be rotated about the axis of the pedestal 2 in one direction whereas if the coiler is of the right-handtype, the coiler must be rotated about the axis of the pedestal '2 in the opposite direction by a predetermined angle.

Thus according 'to this invention means are provided for forming a coupling between the shaft 7 and its associatedhou'sing which readily accommodates angular bodily swinging movement of the coiler in either direction about the axis 'of the pedestal 2. As is best shown in Fig. 4 the vertical .coiler shaft disposed withinthepede's'tal 2 is designated by the numeral 8. Furthermore, as is best shown in Fig. 4, the pedestal generally designated by the numeral 2 comprises a tubular hollow bottom section 9 to the top end of which is welded a center section 10 on which is mounted still another tubular section designated by the numeral 11. Section 11 is welded or otherwise secured atop the center section It Formed near the upper extremity of center section 10 is an inwardly extending flange portion 12 in which a bearing 13 is mounted. Bearing 13 constitutes a means for supporting the sha'ft'8 coaxially within the pedestal 2. Also mounted on the shaft 8 is a beveled pinion 14 which cooperates with a similarly constructed -beveled pinion 15 which is secured to the right-hand extremity of the shaft 7. Shaft 7 is mounted by bearing means 15A in an adapterjelement generally designated by the numeral 16. Adapter 'element 16 is constructed of mating half-sections 17 and 18 which are secured in position by holding means in. the form of bolts 19 and 24 which extend through ears formed on the edges of mating half-sections 17 and I8.

Mating half-section 17 is provided with the transversely disposed housing portion 21 in which a transversely disposed passage is formed and through which the shaft 7 extends. The mating half-section 17 is securely aflixed to part 6 of the card machine by the'bolt-22. A cover plate 18A is removably secured to half-section 17 by bolts 19A andZtlA and normally covers an inspection opening 10A in pedestal center section lit. the

bolts 19 and 20 serve to secure the parts in position while reinforce the center section 10 of pedestal 2.

aosavve The exterior surface 23 of center portion of the pedestal 2 is circular in cross-section and the inner surfaces 24 and 25 of the mating half-sections 17 and 18 respectively and the inner surface of cover plate 18A are likewise configured to conform to the circular configuration of the exterior surface 23. Thus the pedestal 2 may be bodily rotated, if the bolts 19, 20, 19A, and 20A are loosened, without changing the locus of the axis of shaft 8 and of pedestal 2 relative to the drive shaft 7 and adapter 16 comprising mating sections 17, 18, and cover 18A. Pedestal center section 10 is provided with an aperture 25A through which the shaft 7 extends. Opening 25A is constructed sufficiently large in its vertical dimension to accommodate desired adjustment in the elevation of the entire coiler relative to the card machine and the lateral dimension of the opening 25A is made sufficiently large to establish a lost-motion relation between the pedestal 2 and shaft 7 thereby to accommodate any desired angular rotation of pedestal 2 about its axis relative to shaft 7 and adapter 16 comprising mating half-sections 17 and 18.

Since the pedestal comprising parts 9, 10, and 11 is in effect a unitary structure due to the fact that these parts are welded or otherwise permanently secured together and since the head 3 and base 1 are likewise permanently affixed to the ends of the pedestal 2, it will be obvious that operation of the coiler and the card and vibration of the parts will not result in improper adjustment of the individual parts relative to each other or of the coiler relative to the card once the parts are bolted in position.

Furthermore, since the inner surface of the adapter 16 and the exterior surface 23 of the center portion 10 of pedestal 2 are similarly configured, rotation of pedestal 2 and shaft 8 can be effected without affecting the operative relation between pinions 14 and 15. v
